Title: Apparatus for removing foreign matter in raw laver and removal of foreign matter
Inventor: OTSUBO YOSHIMASA
IPC: A23L17/60
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for removing a foreign matter in raw laver, capable of readily and surely removing foreign matter in the raw laver, and further to provide a method for removing the foreign matter. SOLUTION: Drams 2 having sheets 3 installed in the interior of a box-shaped case 1 are arranged at a downward pitch in parallel. A prepared liquid supplied from a pipe 8 into the case 1 overflows the drams 2, and a foreign matter having larger specific gravity and included in the prepared liquid precipitates and attaches the sheets 3. The prepared liquid discharged from the case 1 enters an upper room 13 of a box 11, and a lighter foreign matter is caught by a bubble generated by a bubble-generating means in the prepared liquid. The foreign matter caught by the bubble is sucked out by an exhauster 21. The pure prepared liquid after removing the foreign matter is sent to a production apparatus of a dried laver through a second pipe 17 from a sending-out pipe 15.

Title: Self-adhesive tape, and process cartridge and image formation apparatus using the same
Inventor: FUEI NAOKI
IPC: C09J7/02
Filed: 1992-09-30
Abstract: PURPOSE:To obtain a self-adhesive tape which comprises a tape base and self-adhesive layers for adhering to adherends and has a strong self-adhesive power, is easily peelable when heated, and can be reused as it is when peeled by incorporating a thermally decomposing foaming agent into the self-adhesive layers. CONSTITUTION:A double-coated self-adhesive tape 1 comprises a tape base 1a and self-adhesive layers 1b, 1b formed on both sides of the base 1a. Adherends 2, 3 bonded to each other by self-adhesive power of the self-adhesive layers 1b, 1b. The self-adhesive layers 1b, 1b contain a thermally decomposing foaming agent 1c. A gas generated by the thermal decomposition of the foaming agent 1c forms bubbles, which forms projections at the interface between adherends 2, 3 and the self-adhesive layers 1b, 1b, decreasing the adhesion area and self-adhesive power and facilitating the peeling of the tape 1 from adherends 2, 3. Thus, the adherends 2, 3 are easily separated from each other without leaving behind the have 1a or the self-adhesive layer 1b on the adherends 2, 3.

Title: Surface acoustic wave device
Inventor: SUKAI KAZUYOSHI
IPC: H03H9/25
Filed: 1989-10-31
Abstract: PURPOSE:To reduce the power consumption and to improve the temperature characteristic by applying a reverse bias voltage to a high-density layer of second conduction type formed to a strip on the surface part of a silicon substrate. CONSTITUTION:When a reverse bias voltage +VB is deeply applied to an n<+> (P<+>) diffused area 31 as the high-density layer of second conduction type formed to a strip on the surface part of a silicon substrate 30 of first conduction type, a depletion layer 38 is spread in a p-type silicon substrate 30 as a high-resistance area. Since carrier scarcely exists in this depletion area 38, the carrier density is very reduced, and therefore, the propagation loss of SAW is very reduced without charging of carrier, namely, flow of a current. Thus, the power consumption is reduced to such degree that the current consumption can almost be ignored, and the temperature characteristic is improved.

Title: Specific measuring agent and measuring method for endotoxin
Inventor: AKETAGAWA JUN
IPC: G01N33/579
Filed: 1994-10-25
Abstract: PURPOSE: To enable the measuring of endotoxin in a specimen handily and specifically by making a polycarbonate derivative or a glycelyl derivative of (1→3)-β-D-glucan coexist with a horseshoe amebocyte lysate reagent. CONSTITUTION: In the measuring of endotoxin in a specimen using a horseshoe amebocyte lysate (abbreviated as lysate) reagent, sometimes, a correct result can not be obtained because a G factor based reaction proceeds by a β-glucan sensitive factor possibly contained in the specimen. To solve this problem, a polycarbonate derivative or a glycelyl derivative of (1→3)-β-D-glucan is made to coexist with the lysate to block the G reactor based reaction so strongly by a selection system so that a C factor based reaction by the endotoxin is not inhibited in substance. Thus, a G factor in the lysate is removed by adsorption thereby enabling the measuring of the endotoxin accurately only under the C factor based reaction.

Filed: 1988-11-10
Abstract: PURPOSE:To prevent the excess sheets pulled back between a pick roller and a separating roller from being wrinkled or folded and easily separate them by driving the pick roller and the separating roller with constant torque via a torque limiter. CONSTITUTION:When two sheets 11 and 12 are pulled between a feed belt 3 and a separating roller 4 by the rotation of a pick roller 2, a slip occurs between the two sheets 11 and 12, thus the upper sheet 11 is fed by the feed belt 3, the lower sheet 12 is pulled by the reverse rotation via the primary constant-torque drive of the separating roller 4. The pick roller 2 is also reversely rotated interlockingly with the reverse rotation of the separating roller 4, thereby the lower sheet 12 pulled back is not folded or wrinkled, two sheets 11 and 12 are surely separated without being jammed, and the sheets 11 and 12 are fed one by one.

IPC: B41J2/49
Filed: 1985-12-17
Abstract: PURPOSE:To enable a width of a printing line to be varied to a large extent, by a method wherein a tip portion of a pen is so shaped as to be varied in width due to the rotation of the center axis thereof when viewed from the direction of sliding to vary a pressing force against a transferred member. CONSTITUTION:A cross sectional view of a pen 14' taken along the plane right angles to the axis thereof is made elliptical. Therefore, the pen 14' can select its width then viewed from the side thereof from the width ranging from the maximum to the minimum diameter of the ellipse by being rotated around its axis. The pen 13' is installed to a holder 20 on a frame 19 which is rotated by a pulse motor so that the axis of rotation is opposed against each other and vertical to a transferred member such as a paper. The frame 19 of a spring material formed in a cage-shape is driven in the direction vertical to the surface of the transferred material, i.e. in the direction of arrow B, due to the motion of a voice coil motor 21, thus transmitting to the pen 14' a required pressing force for printing while absorbing a fluctuation in the thickness of the transferred material and an ink ribbon to apply an uniform pressing force for printing to the transferred material.

Title: Voice feature extractor
Inventor: ISO KENICHI
IPC: G10L17/00
Filed: 1987-11-11
Abstract: PURPOSE: To output feature vectors at intervals of an adaptive time by using time variation information of a signal extracted for each channel of a filter bank to adaptively determine the timing of extraction of a feature vector. CONSTITUTION: A variation detection part 1 of each channel calculates the variation with time from the filter output of the channel at each time and outputs it to a variance detection part 2 of the channel. The variance detection part 2 compares the variation with time with a first threshold to determine the variation with time of the channel and outputs it to a feature extraction part 3. This part 3 compares the load sum of outputs of variance detection parts of respective channels with a set second threshold to discriminate whether the output or the filter bank should be extracted as a feature vector or not and outputs the feature vector in accordance with the discrimination result. A threshold setting part 4 sets the value of the second threshold to infinity only for a certain time. Thus, the feature vector is adaptively extracted.
